Removing the zero that precedes the decimal point

I would like to have numbers between 0 and 1 be displayed such as .64 instead of 0.64, i.e. omitting the initial zero.

Since the total number of chars including the decimal point would then be 3, with 2 decimals, I tried

num2str(a,'%3.2f')

as well as

sprintf('%3.2f',a)

(as well as several variations for each), but unexpectedly, they both leave the leading zero before the decimal.

What is the correct formatting tag? Thanks!

Answer 1

[Thorsten]

 strrep(num2str(a), '0.', '.')

[z8080]

Thanks! Is there also a way to do it with the formatting that I was mentioning?

Sorry, I don't know.

No.

strrep(sprintf('%3.2f',a),'0.','.')

Here is a little follow-up in case anyone else has this problem...

I had the same problem as z8080, and I wanted to solve it with a format statement that I could pass to xtickformat or ytickformat. My solution is ugly, but it works:

num2str(100*a,'.%02d')

where the values of 'a' are in the 0--1 range. Or, in my case:

plot(x,100*y,'-V')
ytickformat('.%02d')
